TorgoX quotes someone else, "How many more nations will have to, for example, prove that gun licensing works, or that gay-marriage legislation is a moral imperative, or that health care for all is mandatory for a nation's well being, before America finally looks at itself and says, whoa, damn, we are so silly and small and wrong?"
There's no evidence that gun licensing "works," and even if it did, it would say little if anything about whether or not it is compatible with liberty, which is the entire point.
There's no evidence that gay marriage legislation is a moral imperative, as this is opinion, not fact.
There's no evidence that universal health care is a good thing; indeed, there is more hard evidence against it than for it, as it tends to screw an economy, hurt jobs, decrease the average quality of care, and thereby lower the overall national "well being."
Precisely how "more nations" can "prove" things that no nations are currently proving is a mystery.
